Description

Technical Field

[0001] The utility model relates to the field of metal pipe rolling, in particular to a small metal pipe rolling device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Metal tubes are common in daily life and production, and most metal tubes are processed from metal sheets during the production process. For small metal tubes, the metal sheets required in the processing of small metal tubes are narrow, so it is difficult to make metal tubes by bending, rolling, etc. Most of the time, one end of the metal sheet passes through a forming hole, and the metal tube after the metal sheet is formed is pulled, so that the metal sheet is gradually rolled into a metal tube through the forming hole. How to ensure the stable pulling of the metal sheet during the metal sheet pulling process is a problem to be solved.

[0004] During the forming process of the metal sheet, it is necessary to ensure the flatness of the sheet to prevent the metal sheet from bending during extrusion. Therefore, how to keep the metal sheet at the end flat during the pulling of the metal tube is a problem to be solved. During the entire stretching process, the metal sheet that has not been curled will move around, and there is a possibility that the edge of the sheet will cut the staff. In order to prevent the metal sheet from hurting the staff, how to limit the metal sheet that has not been rolled during the stretching and rolling process to prevent injuries to the staff is a problem to be solved. For one end of the metal sheet, how to start rolling the tube at one end when it is not rolled is a problem to be solved. Utility Model Content

[0022] The utility model is a small metal tube rolling device, the main structure of which includes a shell 1, an extrusion device 2, and a limit device 3. The shell 1 includes a base 4 and an outer shell 5. The base 4 and the outer shell 5 are fixedly connected by threads, so that the other components of the device can be installed and connected. A feed port 6 and a discharge port 7 are provided at both ends of the outer shell 5, and the feed port 6 and the discharge port 7 are arranged on the same horizontal plane, so that the metal sheet enters from the feed port 6 and is discharged from the discharge port 7 after a series of extrusion molding. The outer shell 5 is also provided with a plurality of grooves 17, through holes 18, etc., so that the extrusion device 2 can be connected to the outer shell 5 and fixed accordingly. The outer shell 5 is provided with an extrusion device 2, and the extrusion device 2 is connected to the shell 1.

[0023] The extrusion device 2 includes a support member 8, an extrusion member 9, and a limit member 16. The support member 8 includes a first support member 10 and a second support member 11. The first support member 10 and the second support member 11 are both connected to the base 4, and there is a gap between the first support member 10 and the second support member 11, so that it is convenient to replace various components in the subsequent processing process. The first support member 10 is provided with an arc groove 14, and the arc groove 14 cooperates with the extrusion member 9, so as to play the role of extrusion molding on the metal. The metal processed here is a soft metal such as aluminum and copper. The metal sheet is curled from the sheet to a metal tube through the channel inside the device. The extrusion member 9 includes a first extrusion member 12 and a second extrusion member 13. The first extrusion member 12 cooperates with the first support member 10, and the first extrusion member 12 is provided with an extrusion portion 15 adapted to the arc groove 14, so that the first extrusion member 12 and the first support member 10 play a role of limiting the metal sheet together. The first extrusion member 12 is arranged at the groove 17 of the housing 5, and is connected to the housing 5 through a connecting shaft 19 passing through the through hole 18, so that the first extrusion member 12 can rotate along the connecting shaft 19 on one side, and is easy to replace after damage. The second support member 11 is provided with two second extrusion members 13, and the two second extrusion members 13 cooperate to perform secondary extrusion molding on the extruded metal sheet, and the second extrusion member 13 can be a conical roller, etc., so that the second extrusion member 13 rotates while extruding the metal sheet. For the metal coiled tube extruded by the second extrusion member 13, the contact position of the two extrusion members 9 cannot be well extruded, and there will be gaps, etc., so a stopper 16 is provided at the end of the second extrusion member 13, and a stopper hole is provided on the stopper 16, and the stopper hole is passed through by the metal coiled tube, so that the contact position of the two extrusion members 9 of the metal coiled tube can be extruded, and then discharged from the discharge port 7 on the housing 5. The limiting hole is arranged at another groove 17 on the housing 5 and is fixed together with the first extruded component 12 by a connecting component.

[0024] A limiting device 3 is provided at the feed port 6 of the shell 5. The limiting device 3 limits the feeding process of the metal, preventing the metal sheet at the feed port 6 from moving around due to extrusion. Therefore, the limiting device 3 is provided to prevent the metal sheet from moving around. The limiting device 3 includes a lower roller 20 and an upper roller 21. In order to enable the lower roller 20 and the upper roller 21 to better limit the metal sheet, two lower rollers 20 are provided adjacent to each other, and an upper roller 21 is provided above the middle of the two lower rollers 20, so that the upper roller 21 limits the metal sheet. The two ends of the two lower rollers 20 are connected to the shell 5 by bolts, but a notch 22 is provided at the connection between the upper roller 21 and the shell 5, so that the upper roller 21 can move up and down in the notch 22, so as to be suitable for the coiling of metal sheets of different thicknesses. And the upper roller 21 is fastened to the shell 5 by bolts on both sides. When metal sheets of different thicknesses are used, the extrusion member 9 and the stopper 16 need to be replaced in sequence, so that the extrusion member 9 can extrude and shape the metal sheet.

[0025] Detailed instructions for use:

[0026] One end of the metal sheet is put in from the feed port 6, and then the first extrusion piece 12 is rotated to perform preliminary extrusion molding on the metal sheet, and the metal sheet is continuously put in, so that the metal sheet is extruded by the second extrusion piece 13 and then passes through the circular hole on the limiting piece 16, and finally discharged from the discharge port 7. When one end of the metal sheet is extruded into a metal coil, the metal coil is pulled so that the subsequent metal sheet is extruded and molded by the device. In order to ensure the flatness of the metal sheet extruded by the extrusion piece 9 and the support piece 8, and to prevent the subsequent metal sheet from moving around due to the extrusion of the metal sheet by the first extrusion piece 12 and the first support piece 10, the subsequent metal sheet is limited by the limiting device 3.

[0027] In summary, the device uses the limiting device 3 to enable the metal sheet at the end to be stably moved and pulled when the metal tube is pulled. In addition, the device uses the limiting device 3 to enable the metal sheet that is not extruded during extrusion to maintain a certain degree of flatness, thereby reducing the need for workers to support the metal sheet and reducing the occurrence of scratches on the staff. The device uses the second extrusion member 13 to extrude the metal sheet, so that one end of the metal sheet can be extruded, which facilitates the tube rolling of the metal sheet.
